Use SComm32 to quickly add Serial Communications capabilities to your applications.

See SComm32 Installation for complete instructions - how to install Comm32 on your computer and how to add the SComm32 component to your projects.

The download contains a fully functional trial version of SComm32 as well as sample projects showing you how to use SComm32.

Context sensitive help means that while you're working in your project you can place the cursor on a property and press the F1 key on your keyboard to see the help page describing that property.

The help file also contains information about making RS232 cables and even shows how to make a loop back tester for testing your hardware and debugging your applications.

Which version do you need?

SComm32.ocx

In Visual Basic 6 projects SComm32 is code compatible with MSComm32 so that you can use it in place of MSComm32 without changing any of your code.

Up to 255 Com Ports and improved compatibility/reliability with windows XP, Vista and Windows 7

Comm64.DLL

Comm64.DLL is a proper .Net component compatible with x86, x64 and AnyCPU .Net Projects. Comm64 uses the same syntax as MScomm32 so rewriting or converting a COM project to .NET is a snip.

Why use Comm64.DLL ?

You're experienced with MSComm32 and starting a new project using .Net ? and just don't have time to learn any new syntax.
Converting an existing VB6 project to .Net
Need one component for .Net 32bit, 64bit and 'AnyCPU' projects.
Just don't like Microsoft's 'SerialPort' component.

Visit the Comm64 Website

Older Comm components

Looking for updates for our older Comm ocx version 3.2
(The one with the non-mscomm compatible properties such as ParallelEnable, TxTimeout, DeviceName etc) This is of course still sold, maintained and supported.

Version 3.2.0.114

32bit development in VB6 using the Comm32 Communications OCX ?

Or are you looking for a proper .Net Component ?

Carry on using most of the common and well documented MSComm32 syntax but with a proper .net component allowing you to build x86, x64 and AnyCPU projects using Visual Studio 2005, 2008 and 2010.
